当該多管継手においては、回動係合部材は、連結操作前においては回動防止部材により第1の継手部材支持部材に対する所定の回動位置で回動しないように保持されるので、該第１及び第２の継手部材支持部材を連結する場合には、継手部材と対応継手部材とが相互に対面して整合した継手位置整合状態として相互に近づけるだけで、当該回動係合部材は第１の継手部材支持部材に対して所要の位置とされ、連結のための回動操作ができる状態となる。 In the multi-tubular joint, the rotation engagement member is held by the rotation prevention member so as not to rotate at a predetermined rotation position with respect to the first joint member support member before the coupling operation. When the first and second joint member support members are connected, the rotational engagement member is simply moved closer to each other as a joint position alignment state where the joint member and the corresponding joint member face each other and are aligned. It is in a required position with respect to one joint member support member, and is in a state where a rotation operation for connection is possible.

好ましくは、該回動防止部材が第１の相互係合部を有し、該第２の継手部材支持部材が第２の相互係合部を有しており、
該第１及び第２の継手部材支持部材を該継手位置整合状態にして相互に近づけたときに、該第１の相互係合部と該第２の相互係合部とが係合して、該第１及び第２の継手部材支持部材が該回動方向で相対的に回動しないように保持されるようにすることができる。 Preferably, the rotation preventing member has a first mutual engagement portion, and the second joint member support member has a second mutual engagement portion,
When the first and second joint member support members are brought close to each other in the joint position aligned state, the first mutual engagement portion and the second mutual engagement portion are engaged, The first and second joint member support members can be held so as not to rotate relatively in the rotation direction.

このような構造により、第１及び第２の継手部材支持部材が相対的に回動しない状態で第１及び第２の継手部材支持部材を相互に近づけるようにすることができるので、継手部材と対応継手部材とが連結されるときにこれら継手部材及び対応継手部材に不要な応力がかからないようにすることができる。 With such a structure, the first and second joint member support members can be brought closer to each other in a state where the first and second joint member support members do not relatively rotate. When the corresponding joint member is connected, unnecessary stress can be prevented from being applied to the joint member and the corresponding joint member.

好ましくは、該第１の継手部材支持部材と該回動防止部材との間に設定され、該回動防止部材を該回動係合部材と係合する向きに該連結方向で付勢するスプリングをさらに有するようにすることができる。 Preferably, the spring is set between the first joint member supporting member and the rotation preventing member and biases the rotation preventing member in the connecting direction in a direction to engage the rotation engaging member. Can further be included.

具体的には、該第１の相互係合部と該第２の相互係合部との一方が、該第１の相互係合部と該第２の相互係合部との他方に向かって突出する係合凸部であり、該第１の相互係合部と該第２の相互係合部との該他方が該係合凸部を受け入れる係合凹部であるようにすることができる。 Specifically, one of the first mutual engagement portion and the second mutual engagement portion is directed toward the other of the first mutual engagement portion and the second mutual engagement portion. It is an engaging convex part that protrudes, and the other of the first mutual engaging part and the second mutual engaging part can be an engaging concave part that receives the engaging convex part.

好ましくは、該回動係合部材と該第２の継手部材支持部材には、該回動係合部材を回動することにより該第２の継手部材支持部材を該第１の継手部材支持部材に向けて該連通位置にまで相対的に近づけて、該継手部材と該対応継手部材とを相互連結させるカム機構が設けられているようにすることができる。 Preferably, the second joint member support member is moved to the first joint member support member by rotating the rotation engagement member between the rotation engagement member and the second joint member support member. A cam mechanism for interconnecting the joint member and the corresponding joint member can be provided so as to be relatively close to the communication position.

第１の継手部材支持部材と第２の継手部材支持部材とを複数の継手部材とその対応継手部材とが連通される連通位置にまで近づけるために、回動係合部材と第２の継手部材支持部材とに設けられたカム機構を利用しているので、第２の継手部材支持部材を連通位置にまで近づけるための操作に必要な力を、作業者が直接連通位置にまで押し込む場合に較べて小さくすることが可能となる。 In order to bring the first joint member support member and the second joint member support member close to the communication position where the plurality of joint members and the corresponding joint members communicate with each other, the rotation engagement member and the second joint member Since the cam mechanism provided on the support member is used, the force required for the operation to bring the second joint member support member closer to the communication position is compared with the case where the operator directly pushes the force to the communication position. Can be made smaller.

具体的には、
該カム機構が、該回動係合部材と該第２の継手部材支持部材との一方に設けられたカム輪郭軌道と、該回動係合部材と該第２の継手部材支持部材との他方に設けられ、該カム輪郭軌道に係合するカム突起部と、を有しており、
該回動係合部材を回動することにより該カム突起部が該カム輪郭軌道に沿って動き該第１の継手部材支持部材と該第２の継手部材支持部材とを該連通位置にまで相互に近づけるようにすることができる。 In particular,
The cam mechanism includes a cam contour track provided on one of the rotational engagement member and the second joint member support member, and the other of the rotational engagement member and the second joint member support member. And a cam projection that engages with the cam contour track,
By rotating the rotation engagement member, the cam projection moves along the cam contour track, and the first joint member support member and the second joint member support member are moved to the communication position. It can be made to approach.

さらに具体的には、該回動係合部材と該第２の継手部材支持部材との前記一方が、該第１及び第２の継手部材支持部材を該継手位置整合状態にして相互に近づけたときに、該カム突起部を該回動係合部材の回動方向で見て少なくとも該カム輪郭軌道の一部と重なる位置にまで受け入れる突起部受け入れ部を有するようにすることができる。 More specifically, the one of the rotational engagement member and the second joint member support member brings the first and second joint member support members into the joint position aligned state and brings them close to each other. In some cases, the cam projection may include a projection receiving portion that receives at least a position overlapping with a part of the cam contour track when the cam projection is viewed in the rotation direction of the rotation engagement member.

より具体的には、該回動係合部材が円筒状の形状を有し、該カム突起部が該回動係合部材の内周面に設けられ、
該カム輪郭軌道が該第２の継手部材支持部材の該外周面に設けられており、
該回動防止部材が、円筒状の形状を有し、該回動係合部材の該内周面の内側に該回動係合部材と同軸状に配置されており、
該回動防止部材は、該回動係合部材の該カム突起部を収容して該回動係合部材の回動を防止するカム突起部収容部を有し、該カム突起部収容部は、該第１及び第２の継手部材支持部材が該継手位置整合状態にあるときに該突起部受け入れ部と該連結方向で整合する位置に形成されているようにすることができる。 More specifically, the rotational engagement member has a cylindrical shape, and the cam projection is provided on the inner peripheral surface of the rotational engagement member.
The cam contour track is provided on the outer peripheral surface of the second joint member support member;
The rotation preventing member has a cylindrical shape, and is disposed coaxially with the rotation engaging member inside the inner peripheral surface of the rotation engaging member;
The rotation preventing member has a cam protrusion accommodating portion that receives the cam protrusion of the rotation engaging member and prevents the rotation engaging member from rotating, and the cam protrusion accommodating portion The first and second joint member support members may be formed at positions where they are aligned with the protrusion receiving portion in the connecting direction when the joint position alignment state is established.

連結操作前において、回動係合部材は、回動防止部材の突起部収容部によって、カム突起部が突起部受け入れ部と連結方向で整合する位置で回動しないように保持されるので、第１及び第２の継手部材支持部材が継手位置整合状態にない状態では、第１及び第２の継手部材支持部材を連通位置にまで互いに近づけることができないようにすることができる。従って、継手部材と対応継手部材とが正しく整合した状態でのみ連結可能となるので、対応しない継手同士が連結される誤接続を防止することができる。 Before the connecting operation, the rotation engaging member is held by the protrusion accommodating portion of the rotation preventing member so that the cam protrusion does not rotate at a position aligned with the protrusion receiving portion in the connecting direction. In a state where the first and second joint member support members are not in the joint position alignment state, the first and second joint member support members cannot be brought close to each other to the communication position. Therefore, since it becomes possible to connect only when the joint member and the corresponding joint member are correctly aligned, it is possible to prevent erroneous connection in which joints that do not correspond to each other are connected.

好ましくは、該回動係合部材は、２つの該カム突起部を当該回動係合部材の該内周面の直径方向で互いに対向しない位置に有し、該第２の継手部材支持部材は該２つのカム突起部をそれぞれ受け入れる２つの該突起部受け入れ部と、該２つのカム突起部のそれぞれに対応する該カム輪郭軌道と、を有するようにすることができる。 Preferably, the rotational engagement member has two cam projections at positions that do not face each other in the diameter direction of the inner peripheral surface of the rotational engagement member, and the second joint member support member is It is possible to have two protrusion receiving portions that respectively receive the two cam protrusions, and the cam contour track corresponding to each of the two cam protrusions.

このような構成により、第１の継手部材支持部材と第２の継手部材支持部材とを連結位置にまで近づけることが可能となる継手位置整合状態を一つの状態に定めることができる。 With such a configuration, the joint position alignment state that enables the first joint member support member and the second joint member support member to be close to the coupling position can be determined as one state.

好ましくは、該カム輪郭軌道が、
該回動係合部材の回動方向に延びる円周方向部であって、該カム突起部が該円周方向部と係合しているときには、該第１及び第２の継手部材支持部材を該継手部材と該対応継手部材とが連通されていない非連通位置に保持する円周方向部と、
該円周方向部から周方向で該第１の継手部材支持部材に対面する側から遠ざかる方向に傾斜して延びるカム作用部であって、該カム突起部が該カム作用部に沿って動かされることにより、該第１及び第２の継手部材支持部材を該非連通位置と該連通位置との間で近づけたり離したりするようにするカム作用部と、
を有しているようにすることができる。 Preferably, the cam profile trajectory is
When the cam protrusion is engaged with the circumferential portion, the first and second joint member supporting members are arranged in a circumferential direction extending in the turning direction of the turning engagement member. A circumferential portion that holds the joint member and the corresponding joint member at a non-communication position where they are not in communication;
A cam action portion extending in a direction inclined away from a side facing the first joint member support member in the circumferential direction from the circumferential direction portion, and the cam projection portion is moved along the cam action portion A cam action portion for bringing the first and second joint member support members closer to or away from the non-communication position and the communication position;
It can be made to have.

カム輪郭軌道をこのような形状とすることで、特に連結された継手部材と対応継手部材とを切り離す際に、カム突起部が円周方向部と係合した非連通状態において、第１及び第２の継手部材支持部材の連結方向での位置を保持しつつ配管内に残った流体を放出することが可能となる。これにより、第１の継手部材支持部材と第２の継手部材支持部材とが、放出される気体から受ける力により飛ばされることを防止すること可能となる。 By forming the cam contour track in such a shape, in particular, when the coupled joint member and the corresponding joint member are separated from each other, in the non-communication state in which the cam protrusion is engaged with the circumferential direction portion, It becomes possible to discharge the fluid remaining in the pipe while maintaining the position in the connecting direction of the two joint member support members. Thereby, it becomes possible to prevent the first joint member support member and the second joint member support member from being blown by the force received from the released gas.

好ましくは、該カム突起部が、回転しながら該カム輪郭軌道と係合するローラを有するようにすることができる。 Preferably, the cam projection may have a roller that engages the cam profile track while rotating.

ローラによってカム輪郭軌道との係合が滑らかになり、回動係合部材を回動させる際に必要な力をさらに低減することが可能となる。 The engagement with the cam contour track is smoothed by the roller, and it is possible to further reduce the force required to rotate the rotation engagement member.

図６及び図７に示すように、回動防止部材６０は円筒状の形状を有し、上端部６２から下方に延びるピンガイド穴６４を有する。回動防止部材６０は、図８及び９に示すように、ピンガイド穴６４がソケット支持部材２０の外周面２２に設けられたピン嵌合穴３４に嵌合されたガイドピン３８を受け入れるようにしてソケット支持部材２０の外周面２２上に配置されている。回動防止部材６０は、ピンガイド穴６４がガイドピン３８と摺動係合することにより、ソケット１３とプラグ１７とが相互連結される連結方向には変位可能であるが、回動係合部材４０の回動方向には変位不能となっている。回動防止部材６０の下端部６６には、ローラ５６を収容可能な大きさとされたローラ収容凹部（カム突起部収容部）６８が設けられている。このローラ収容凹部６８がローラ５６を収容しているときには、ローラ５６がローラ収容凹部６８に係合して回動係合部材４０は回動できない状態に保持される。なお、ローラ５６を用いていない場合には、このローラ収容凹部６８はカム突起部としてのボルト５０を直接収容する。回動防止部材６０の下端部６６にはさらに係合凹部（第１の相互係合部）７０が設けられていて、後述するプラグ支持部材８０の係合凸部（第２の相互係合部）８８と係合して、ソケット支持部材２０とプラグ支持部材８０との相対的な回動を阻止するようにもなっている。図１に示すように、回動防止部材６０の外周面６１の段部に形成されたスプリング支持面７２とソケット支持部材２０が有する円環状支持部３０の下面に形成されたスプリング支持面３０−２との間にはスプリング７４が設定されている。このスプリング７４によって回動防止部材６０はソケット支持部材２０に対して下方に向かって、下端部６６のローラ収容凹部６８がローラ５６に当接する位置にまで移動する。 As shown in FIGS. 6 and 7, the rotation preventing member 60 has a cylindrical shape and has a pin guide hole 64 extending downward from the upper end portion 62. As shown in FIGS. 8 and 9, the rotation preventing member 60 receives the guide pin 38 in which the pin guide hole 64 is fitted in the pin fitting hole 34 provided in the outer peripheral surface 22 of the socket support member 20. The socket support member 20 is disposed on the outer peripheral surface 22. The rotation preventing member 60 can be displaced in the connecting direction in which the socket 13 and the plug 17 are interconnected by the pin guide hole 64 slidingly engaged with the guide pin 38. 40 cannot be displaced in the direction of rotation. The lower end 66 of the rotation preventing member 60 is provided with a roller accommodating recess (cam protrusion accommodating portion) 68 that is sized to accommodate the roller 56. When the roller accommodating recess 68 accommodates the roller 56, the roller 56 is engaged with the roller accommodating recess 68 and the rotation engaging member 40 is held in a state where it cannot rotate. When the roller 56 is not used, the roller accommodating recess 68 directly accommodates the bolt 50 as a cam projection. The lower end portion 66 of the rotation preventing member 60 is further provided with an engagement recess (first mutual engagement portion) 70, and an engagement convex portion (second mutual engagement portion) of the plug support member 80 described later. ) 88 to prevent relative rotation between the socket support member 20 and the plug support member 80. As shown in FIG. 1, the spring support surface 30-formed on the spring support surface 72 formed on the step portion of the outer peripheral surface 61 of the rotation preventing member 60 and the lower surface of the annular support portion 30 included in the socket support member 20. A spring 74 is set between the two. With this spring 74, the rotation preventing member 60 moves downward with respect to the socket support member 20 to a position where the roller accommodating recess 68 at the lower end 66 contacts the roller 56.

図４及び図５に示すように、プラグ支持部材８０は円筒状部分８０−１とその下の板状部分８０−２とからなり、板状部分８０−２に形成された４つの取付穴８０−３により所定の場所にボルト等で固定できるようになっている。プラグ支持部材８０は、その上面８２から下面８４にまで貫通する６つのプラグ支持穴８６を有し、各プラグ１７は下面８４側から各プラグ支持穴８６内に挿入され、各プラグ１７のプラグ支持部材８０の上面８２から出た位置にストップリング９８を取り付けることによりプラグ支持部材８０に固定される（図１）。プラグ支持部材８０の上面８２には、上方に向かって突出する係合凸部８８が形成されており、上述のように、回動防止部材６０の係合凹部７０と係合することにより、ソケット支持部材２０をプラグ支持部材８０に対して回動係合部材４０の回動方向で相対的に回動しないように保持する。また、係合凸部８８を係合凹部７０と係合させることにより、ソケット支持部材２０とプラグ支持部材８０とが各ソケット１３とプラグ１７とが軸線方向２，４で相互に対面して整合した継手位置整合状態に位置合わせされるようにもなっている。プラグ支持部材８０の外周面８１の上端位置には、ボルト５０、図示の例では、ボルト５０に取り付けられているローラ５６が当該プラグ支持部材８０の中心軸線方向で通過可能な大きさのローラ受け入れ溝（突起部受け入れ部）９０が形成されている。回動防止部材６０に設けられた上述のローラ収容凹部６８は、ソケット支持部材２０とプラグ支持部材８０とが継手位置整合状態にあるときに、このローラ受け入れ溝９０と連結方向で整合する位置に形成されている。さらにこのローラ受け入れ溝９０に連接したカム溝（カム輪郭軌道）９４が、外周面８１上で周方向に沿って形成されている。上述のカム機構は、回動係合部材４０のボルト５０、図示の例ではボルト５０に取り付けられているローラ５６と、プラグ支持部材８０のカム溝９４と、によって構成されている。カム溝９４は、図１１Ａに示すように、ローラ受け入れ溝９０に連接し回動係合部材４０の回動方向に沿って伸びる第１円周方向部９４−１と、それに続き周方向でプラグ支持部材８０の上面８２から遠ざかる方向に緩やかに傾斜したカム作用部９４−２と、さらにこれに続き回動係合部材４０の回動方向に沿って伸びる第２円周方向部９４−３と、その先に設けられたローラ受部９４−４とにより構成されている。ここで「周方向」とは、外周面８１の中心軸線を中心とする円周に沿う方向及び該円周に対して斜めの方向を含む方向、すなわち該中心軸線に沿う方向以外の方向で外周面８１に沿う方向と意味する。また「回動方向」とは、該回動係合部材４０が回動する方向、すなわち回動係合部材４０の回動中心軸を中心とする円周に沿う方向を意味し、該円周に対して斜めの方向は含まないことを意味する。 As shown in FIGS. 4 and 5, the plug support member 80 includes a cylindrical portion 80-1 and a plate-like portion 80-2 below it, and four mounting holes 80 formed in the plate-like portion 80-2. -3 can be fixed to a predetermined place with a bolt or the like. The plug support member 80 has six plug support holes 86 penetrating from the upper surface 82 to the lower surface 84, and each plug 17 is inserted into each plug support hole 86 from the lower surface 84 side. A stop ring 98 is attached to a position protruding from the upper surface 82 of the member 80 to be fixed to the plug support member 80 (FIG. 1). The upper surface 82 of the plug support member 80 is formed with an engaging convex portion 88 that protrudes upward. By engaging with the engaging concave portion 70 of the rotation preventing member 60 as described above, the socket The support member 20 is held so as not to rotate relative to the plug support member 80 in the rotation direction of the rotation engagement member 40. Further, by engaging the engaging convex portion 88 with the engaging concave portion 70, the socket support member 20 and the plug support member 80 are aligned so that the socket 13 and the plug 17 face each other in the axial directions 2 and 4. The joint is aligned to the joint position alignment state. At the upper end position of the outer peripheral surface 81 of the plug support member 80, the bolt 50, in the illustrated example, the roller 56 attached to the bolt 50 can receive a roller having such a size that can pass in the direction of the central axis of the plug support member 80. A groove (projection receiving part) 90 is formed. The roller receiving recess 68 provided in the rotation preventing member 60 is positioned so as to align with the roller receiving groove 90 in the connecting direction when the socket support member 20 and the plug support member 80 are in the joint position alignment state. Is formed. Further, a cam groove (cam contour track) 94 connected to the roller receiving groove 90 is formed on the outer peripheral surface 81 along the circumferential direction. The cam mechanism described above is constituted by the bolt 50 of the rotation engaging member 40, the roller 56 attached to the bolt 50 in the illustrated example, and the cam groove 94 of the plug support member 80. As shown in FIG. 11A, the cam groove 94 includes a first circumferential portion 94-1 connected to the roller receiving groove 90 and extending along the rotation direction of the rotation engagement member 40, followed by a plug in the circumferential direction. A cam action portion 94-2 that is gently inclined in a direction away from the upper surface 82 of the support member 80, and a second circumferential direction portion 94-3 that extends along the turning direction of the turning engagement member 40 following this. , And a roller receiving portion 94-4 provided at the tip thereof. Here, the “circumferential direction” refers to a direction along the circumference centering on the central axis of the outer peripheral surface 81 and a direction including a direction oblique to the circumference, that is, a direction other than a direction along the central axis. The direction along the surface 81 is meant. The “rotation direction” means a direction in which the rotation engagement member 40 rotates, that is, a direction along the circumference around the rotation center axis of the rotation engagement member 40. This means that the oblique direction is not included.

次に、ソケット支持部材２０とプラグ支持部材８０とを相互連結する過程を図１０Ａ乃至図１１Ｃに基づき説明する。まず、ソケット支持部材２０とプラグ支持部材８０とを各ソケット１３とプラグ１７とが相互に対面して整合した継手位置整合状態とし、回動防止部材６０の係合凹部７０とプラグ支持部材８０の係合凸部８８とが係合するように配置する（図１０Ａ）。このとき、回動防止部材６０のローラ収容凹部６８によって所定の回動位置に位置決めされて回動しないように保持されているローラ５６の一部が、プラグ支持部材８０の外周面８１に形成されたローラ受け入れ溝９０に既に受け入れられている（図１１Ａ）。上述のように２つのローラ５６は径方向で対向しない位置に配置されているので、各ローラ５６が各ローラ受け入れ溝９０に受け入れられるときのプラグ支持部材２０に対するソケット支持部材８０の向きは一つに定まる。このようにすることにより、ソケット支持部材２０とプラグ支持部材８０とが異なる向きで連結されるような誤連結が起こることを防止している。なお、ソケット支持部材２０とプラグ支持部材８０とが継手位置整合状態にない不適切な配置状態でソケット支持部材２０とプラグ支持部材８０とを相互に近づけようとすると、ローラ５６がプラグ支持部材８０の上面８２に当接するので、ソケット支持部材２０とプラグ支持部材８０とを連通位置にまで近づけることはできない。またこのとき、回動防止部材６０はローラ収容部６８とローラ５６との係合が解除される位置にまでは変位しないので、回動係合部材４０の回動防止状態は解除されないままとなる。係合凹部７０と係合凸部８８とが係合し、且つローラ５６の一部がローラ受け入れ溝９０に受け入れられている状態（図１０Ａ）でソケット支持部材２０をプラグ支持部材８０に対してスプリング７４の付勢力に抗して押し付けると、ソケット支持部材２０は、ローラ５６がプラグ支持部材８０のカム溝９４の下面９６に当接する位置にまで移動する（図１０Ｂ、図１１Ｂ）。このときプラグ１７の先端の連結部１８の一部が対応するソケット１３の連結部１５の中に挿入されているが、ソケット１３とプラグ１７とはまだ完全には連通しておらず間に隙間がある状態となっている。また、ソケット１３のバルブ１４はまだ閉じた状態となっている。プラグ支持部材８０の上面８２と係合している回動防止部材６０は、プラグ支持部材８０によってスプリング７４の付勢力に抗して上方に押されて、ローラ５６をローラ収容凹部６８から完全に解放した状態となる。従って、回動係合部材４０は回動可能な状態となる。ここから回動係合部材４０を上方から見て時計回りに回動させると、ローラ５６がまずカム溝９４の第１円周方向部９４−１内に入る。この時点では、ソケット支持部材２０とプラグ支持部材８０との距離は図１０Ｂの状態から変化していない。すなわち、ソケット支持部材２０とプラグ支持部材８０とは、ソケット１３とプラグ１７とが近接はしているが連通はしていない、非連通位置にある。回動係合部材４０をさらに回動させると、ローラ５６は、傾斜したカム作用部９４−２（具体的には、カム作用部９４−２のソケット支持部材２０側の側面）に係合し、このカム作用部９４−２に沿って進む。それに伴い、ソケット支持部材２０とプラグ支持部材８０とが徐々に近づけられていく。ローラ５６が第２円周方向部９４−３にまで至る途中で、まずソケット１３とプラグ１７とが連通され、その後にバルブ１４が開いて、ソケット支持部材２０とプラグ支持部材８０とが、ソケット１３とプラグ１７との相互連結が完了した連通位置となる。さらに回動係合部材４０を回動させると、ローラ５６がローラ受部９４−４と係合して、回動係合部材４０の回動が抑制された状態となり、連結操作が完了する（図１０Ｃ、図１１Ｃ）。 Next, a process of interconnecting the socket support member 20 and the plug support member 80 will be described with reference to FIGS. 10A to 11C. First, the socket support member 20 and the plug support member 80 are brought into a joint position alignment state in which the sockets 13 and the plugs 17 face each other and are aligned, and the engagement recess 70 of the rotation preventing member 60 and the plug support member 80 are aligned. It arrange | positions so that the engagement convex part 88 may engage (FIG. 10A). At this time, a part of the roller 56 that is positioned at a predetermined rotation position by the roller receiving recess 68 of the rotation prevention member 60 and is held so as not to rotate is formed on the outer peripheral surface 81 of the plug support member 80. It has already been received in the roller receiving groove 90 (FIG. 11A). As described above, since the two rollers 56 are arranged at positions that do not oppose each other in the radial direction, the orientation of the socket support member 80 with respect to the plug support member 20 when each roller 56 is received in each roller receiving groove 90 is one. Determined. By doing so, it is possible to prevent erroneous connection such that the socket support member 20 and the plug support member 80 are connected in different directions. Note that if the socket support member 20 and the plug support member 80 are brought close to each other in an inappropriate arrangement state in which the socket support member 20 and the plug support member 80 are not in the joint position alignment state, the roller 56 causes the plug support member 80 to move closer to each other. Therefore, the socket support member 20 and the plug support member 80 cannot be brought close to the communication position. At this time, since the rotation preventing member 60 is not displaced to the position where the engagement between the roller accommodating portion 68 and the roller 56 is released, the rotation preventing state of the rotation engaging member 40 is not released. . The socket support member 20 is moved with respect to the plug support member 80 in a state where the engagement concave portion 70 and the engagement convex portion 88 are engaged and a part of the roller 56 is received in the roller receiving groove 90 (FIG. 10A). When pressed against the urging force of the spring 74, the socket support member 20 moves to a position where the roller 56 contacts the lower surface 96 of the cam groove 94 of the plug support member 80 (FIGS. 10B and 11B). At this time, a part of the connecting portion 18 at the tip of the plug 17 is inserted into the connecting portion 15 of the corresponding socket 13, but the socket 13 and the plug 17 are not yet completely communicated with each other. There is a state. Further, the valve 14 of the socket 13 is still closed. The rotation preventing member 60 engaged with the upper surface 82 of the plug support member 80 is pushed upward against the urging force of the spring 74 by the plug support member 80, so that the roller 56 is completely removed from the roller receiving recess 68. It is in a released state. Therefore, the rotation engaging member 40 is in a rotatable state. When the rotation engaging member 40 is rotated clockwise as viewed from above, the roller 56 first enters the first circumferential portion 94-1 of the cam groove 94. At this time, the distance between the socket support member 20 and the plug support member 80 has not changed from the state of FIG. 10B. That is, the socket support member 20 and the plug support member 80 are in a non-communication position where the socket 13 and the plug 17 are close but not in communication. When the rotation engagement member 40 is further rotated, the roller 56 engages with the inclined cam action portion 94-2 (specifically, the side surface of the cam action portion 94-2 on the socket support member 20 side). Then, it proceeds along this cam action portion 94-2. Accordingly, the socket support member 20 and the plug support member 80 are gradually brought closer to each other. In the middle of the roller 56 reaching the second circumferential portion 94-3, the socket 13 and the plug 17 are first communicated, and then the valve 14 is opened, and the socket support member 20 and the plug support member 80 are connected to the socket. 13 and the plug 17 are connected to each other. When the rotation engagement member 40 is further rotated, the roller 56 is engaged with the roller receiving portion 94-4, and the rotation of the rotation engagement member 40 is suppressed, and the coupling operation is completed ( FIG. 10C and FIG. 11C).

ソケット支持部材２０とプラグ支持部材８０とを切り離す際には、回動係合部材４０を連結操作時とは逆方向（上から見て反時計回り）に回動する。ソケット支持部材２０とプラグ支持部材８０とは、スプリング７４の付勢力、及び配管内に圧縮流体がある場合にはその圧力により、互いに離される方向に力を受けているので、回動係合部材４０を回動させてローラ５６がカム作用部９４−２にまで至ると、ソケット支持部材２０とプラグ支持部材８０とは連結方向で離されていく。ローラ５６がカム作用部９４−２の上部側面と係合しながら移動している途中の段階で、まずバルブ１４が閉じ、次にソケット１３とプラグ１７との連通が解除される。このときバルブ１４が設けられていないプラグ１７側の内部流体が連結部１８から勢いよく放出されるので、プラグ支持部材８０はソケット支持部材２０から離される方向に大きな力を受ける。この力により回動係合部材４０は、ローラ５６がカム作用部９４−２に沿って第１円周方向部９４−１に係合する位置までは回動されるが、ローラ５６が第１円周方向部９４−１と係合した以降は、内部流体の放出による連結方向の力をローラ５６と第１円周方向部９４−１とによって受けるので、ソケット支持部材２０とプラグ支持部材８０とは非連通位置に保持されてそれ以上は離されない。プラグ１７側の内部流体が十分に放出されるのを待ってからさらに回動係合部材４０を回動させ、ローラ５６がローラ受け入れ溝９０と連結方向で整合する位置にまで至ると、プラグ支持部材２０はスプリング７４の付勢力によりソケット支持部材８０から離されて、ソケット支持部材２０とプラグ支持部材８０との切り離し操作が完了する。回動防止部材６０は、スプリング７４によって付勢されて、ローラ収容凹部６８にローラ５６を収容して保持した状態となり、これにより回動係合部材４０は再びソケット支持部材２０に対して所定の回動位置で回動が防止された状態となる。 When the socket support member 20 and the plug support member 80 are separated, the rotation engagement member 40 is rotated in the opposite direction (counterclockwise as viewed from above) from the time of the coupling operation. Since the socket support member 20 and the plug support member 80 receive forces in the directions away from each other due to the biasing force of the spring 74 and the pressure when there is compressed fluid in the pipe, the rotation engagement member When the roller 40 reaches the cam action portion 94-2 by rotating the motor 40, the socket support member 20 and the plug support member 80 are separated in the connecting direction. In the middle of the movement of the roller 56 while engaging the upper side surface of the cam action portion 94-2, the valve 14 is first closed, and then the communication between the socket 13 and the plug 17 is released. At this time, since the internal fluid on the side of the plug 17 where the valve 14 is not provided is vigorously released from the connecting portion 18, the plug support member 80 receives a large force in a direction away from the socket support member 20. With this force, the rotation engaging member 40 is rotated to the position where the roller 56 is engaged with the first circumferential direction portion 94-1 along the cam action portion 94-2. After engaging with the circumferential portion 94-1, the force in the connecting direction due to the discharge of the internal fluid is received by the roller 56 and the first circumferential portion 94-1, so that the socket support member 20 and the plug support member 80 are connected. Is held in a non-communication position and is no longer separated. After waiting for the internal fluid on the plug 17 side to be sufficiently discharged, the rotating engagement member 40 is further rotated, and when the roller 56 reaches a position aligned with the roller receiving groove 90 in the connecting direction, the plug support The member 20 is separated from the socket support member 80 by the urging force of the spring 74, and the separation operation of the socket support member 20 and the plug support member 80 is completed. The rotation preventing member 60 is urged by the spring 74 and is in a state where the roller 56 is accommodated and held in the roller accommodating recess 68, whereby the rotation engaging member 40 is again in a predetermined state with respect to the socket support member 20. It will be in the state by which rotation was prevented in the rotation position.

このように本発明に係る多管継手１０は、ソケット１３とプラグ１７とを連結させるための操作部である回動係合部材４０が、回動防止部材６０によって、ローラ５６がプラグ支持部材８０のカム溝９４に受け入れられる位置で保持されているので、連結操作時に回動係合部材４０の位置合わせを行う必要がない。このような構成により、ソケット支持部材２０とプラグ支持部材８０との連結操作を迅速に行うことが可能となる。また、カム機構を利用してソケット支持部材２０とプラグ支持部材８０とを非連通位置から連通位置にまで近づけるようにしていて、カム作用部９４−２の傾斜を緩やかなものに設定することによってプラグ支持部材８０の変位量に対する回動係合部材４０の回動量を大きくできるので、連結操作に要する作業者の力を小さくすることも可能となる。特にバルブ１４を有するソケット１３側の流路内が加圧された状態で連結操作を行う場合には、加圧状態にあるバルブ１４を押し開けるために比較的に大きな力が必要になるが、このようなカム機構を利用することにより、加圧状態での連結操作でも作業者は大きな力を要することなく連結作業を行うことが可能となる。 As described above, in the multi-pipe joint 10 according to the present invention, the rotation engaging member 40 which is an operation unit for connecting the socket 13 and the plug 17 is provided by the rotation preventing member 60, and the roller 56 is provided by the plug support member 80. Therefore, it is not necessary to align the rotation engaging member 40 during the coupling operation. With such a configuration, the connection operation between the socket support member 20 and the plug support member 80 can be performed quickly. Further, by using the cam mechanism, the socket support member 20 and the plug support member 80 are brought close to the communication position from the non-communication position, and the inclination of the cam action portion 94-2 is set to be gentle. Since the rotation amount of the rotation engagement member 40 with respect to the displacement amount of the plug support member 80 can be increased, the operator's force required for the coupling operation can be reduced. In particular, when performing the connecting operation in a state where the inside of the flow path on the socket 13 side having the valve 14 is pressurized, a relatively large force is required to push open the valve 14 in the pressurized state. By using such a cam mechanism, an operator can perform a connecting operation without requiring a large force even in a connecting operation in a pressurized state.

なお、本実施形態においては、６つのソケット１３とプラグ１７とが円形状に配置されているが、ソケット１３とプラグ１７の配置数及び配置位置はどのようにしてもよい。また、本実施形態におけるソケット支持部材２０側にプラグ１７を設け、プラグ支持部材８０側にソケット１３を設けるようにしてもよい。さらには一方の支持部材にソケット１３とプラグ１７を混合して配置し、他方の支持部材にそれらに対応するソケット１３とプラグ１７とを配置するようにしてもよい。本実施形態ではソケット１３にバルブ１４が設けられているが、プラグ１７側に設けるようにしてもよいし、ソケット１３とプラグ１７との両方に設けるようにしてもよい。 In the present embodiment, the six sockets 13 and the plugs 17 are arranged in a circular shape.

本実施形態において、カム機構は回動係合部材４０の内周面４２から突出したボルト５０と該ボルトに取り付けたローラ５６とからなるカム突起部と、プラグ支持部材８０の外周面８１に形成されたカム溝９４からなるカム輪郭軌道とによって構成されているが、回動係合部材４０の内周面４２にカム溝９４を形成し、プラグ支持部材８０の外周面８１にボルト５０若しくはボルト５０とローラ５６を設けるようにすることもできる。また、上記実施例ではカム溝９４をカム輪郭軌道として示したが、カム輪郭軌道としては、溝ではなく、上述のカム溝と同様のカム輪郭曲線を備えるレール上のもとすることもできる。 In the present embodiment, the cam mechanism is formed on the cam projection portion including the bolt 50 protruding from the inner peripheral surface 42 of the rotation engaging member 40 and the roller 56 attached to the bolt, and the outer peripheral surface 81 of the plug support member 80. The cam groove 94 is formed on the inner peripheral surface 42 of the rotary engaging member 40, and the bolt 50 or the bolt is formed on the outer peripheral surface 81 of the plug support member 80. 50 and roller 56 may be provided.
